Abstract
Apparatus for creating a current in a swimming pool against which a swimmer can swim-in-place in the pool, the pool comprising a water basin having an upper rim and being filled with water up to a predetermined upper level below the rim, the apparatus comprising a propeller and a motor mechanism for driving the propeller; a mechanism connected to the propeller for positioning the propeller at selected depth below the upper level of water in the basin such that when the propeller is driven the propeller generates a current of water flowing in a selected direction between about 0.1 and about 4 feet below the upper level of water in the basin; a mechanism for immovably mounting the positioning mechanism at a selected position around the rim of the basin, the positioning mechanism being connected to the mounting mechanism; the mechanism for mounting being portable such that the propeller and positioning mechanism are transportable to and away from the rim of the basin; the mounting mechanism being immovably mountable at the selected position around the rim of the pool; a rigid protective housing mounted around the propeller such that the propeller is completely surrounded by the housing, the protective housing being impenetrable by a human body part and being permeable to the current of the water flow generated by the propeller when driven.
